Chemical Fiber Co., Ltd. , Jiangsu Fergus Application
Power Quality Condition
Fiber Co., Ltd. , Jiangsu Fergus spinning workshop , the workshop is equipped with a large number of drive load polyester. According to pre- load calculation and assessment of power quality, the power factor arrives 0.92, but the harmonic obviously exceed the standard, mainly in the 5 , 7th harmonics.
According to analysis and calculation, one set of YSVC-L-0.4-1000 / 600kVar dynamic compensation filter was installed on each low voltage bus. Filter branch effectively compensate capacity is 540KVar, installed capacity is 1000KVar, The filter branch had branch of 5 and 7 times, with configure 600KVar phased adjustable reactor.
The compensation device improved the power quality effectively, harmonic filtering rate achieved 65 %.
